Add a way to retrieve values from .git/config files
This introduces the PBGitConfig class. It is KVC compliant as far as I can see, in that you can actually bind to it in IB and use ValueForKeyPath to retrieve values. It currently only handles strings; it should be possible to add functions to process booleans and numbers to it.
